Hello all, many years ago I trained at college to be an aquaculture technician. Apparently my big problem was that I am the wrong sex...

Anyway the interest in aquaculture has remained and been renewed by hearing about aquaponics. Now my husband is cowering and the children are being ignored as I trawl the net looking for prices and bargains for the gear that we will need.

A technical query for those in the know. Are steel sided & lined swimming pools suitable for the fish pond? Or do you have to go food grade?

Hey Jaymie. Welcome, from one female to another. You are not the wrong sex, just ahead of your time. As you can see from the posts, aquaculture is a growing art. I first learned of aquaculture 14 years ago, and am now getting to put the dream into action; the love of this never goes away. Enjoy your new journey.
You do want to incorporate food grade products into your system, at least nothing toxic.

Hi Jaymie,
Welcome...O o!
Once you come in here you are addicted, so be warned.
There has been a lot of discussion about liners.
They must be food grade but you should checkout some posts that relate to this subject. Such as the following.
Questionable construction materials and/or leaching
Good luck....poor old hubby

yeh, its a tough one..........and sometime you need to pick the lesser of two evils. Keeping in mind that pondliners are not necessarily food grade, but lots of people are using them.........know what i mean?

which ever way you go i'm sure the findal products will be a hell of a lot healthier than the commercial equiv. i read some where that some produce is sprayed up to 17 times from planting by the time it reaches the shelves.

It's not just the lesser of two evils, it's also the lesser of two prices.
The pool is $330 and the equivalent tank is $1500.
Unless someone knows a cheaper alternative for a pond/tank approx 3m diam x 1m deep.....

Was that 1500 for a stand-alone tank?
You could check the price of a potable water liner for the pool.
Rainwater tank liners aren't that Xe are they?
It will cost me 1500 for a 20000 gal liner that's 8m X 2.1

Now worries, just wanted to sound smart we were calling them all sorts of silly things until Garddy Donaldson set us straight

They are the big white containainers in a cage that you seen on the back of transport trucks. You can pick them up for approx $100 from recycling yards. Some one in your state no doubt knows of a place, give them a day to see your post and someone might put you onto a source. There has been much discussion about the IBC's (an incentive to get through all the posts )

Look at my system thread and you'll see about 30cms of mine, the rest i sunk into the ground for thermal insualtion and to facilitate gravity return

Right, now I know what you're talking about. I have seen them hurtling by on the highway.
My husband has been asking a neighbour who works for the army about the possibility of any out-of-service water tanks from them. We'll see what happens there.

I'm pulling in favours from all around, on the scrounge. The guy across the road also has blue dums he can give us.
But first I have to clean up the yard so I can fit this project in... Any one want to whipper snip the 8 foot spear grass for me? there's not that much of it...
